摘要： A method for improving the efficiency for an optoelectronic device, such as semiconductor lasers, Superluminescence Light Emitting Diodes (SLDs), Gain Chips, optical amplifiers is disclosed, see FIG. 4B. In accordance with the principles of the invention, at least one blocking layer (70) is interposed at the interface between materials composing the device. The at least one blocking layers creates a barrier that prevents the leakage of electrons from a device active region contained in the waveguide region, to a device clad region (66). In one aspect of the invention, a blocking layer (70) is formed at the junction of the semiconductor materials having different types of conductivity. The blocking layer prevents electrons from entering the material of a different polarity. In another aspect of the invention, a low-doped or undoped region (64) is positioned adjacent to the blocking layer (70) to decrease optical losses.

摘要： A semiconductor laser diode having increased efficiency and therefore increased power output. The laser diode includes a body of a semiconductor material having therein a waveguide region which is not intentionally doped so as to have a doping level of no greater than about 5×1016/cm3. Within the waveguide region is means, such as at least one quantum well region, for generating an optical mode of photons. Clad regions of opposite conductivity type are on opposite sides of the waveguide region. The thickness of the waveguide region, a thickness of at least 500 nanometers, and the composition of the waveguide and the clad regions are such so as to provide confinement of the optical mode in the waveguide region to the extent that the optical mode generating does not overlap into the clad regions from the waveguide region more than about 5%.

摘要： A thermophotovoltaic cell and diode photodetector having improved open circuit voltage and high internal efficiency includes a semiconductor body having regions of n-type conductivity and p-type conductivity adjacent each other to form a p-n junction therebetween. The p-type region is of a material having a band gap which will absorb black-body radiation and the n-type region is of a material having a wider band gap than that of the p-type region. This forms a heterojunction between the two regions. The region of n-type region has a doping level which is an order of magnitude less than the doping level in the p-type region. This structure forms a cell having a space charge region in the n-type region.

摘要： A semiconductor laser device with separated, highly-strained quantum wells employs highly-strained ternary and quasi-ternary compounds as material for each quantum well. A first device structure includes a quantum well composition range extended from strained ternary compounds employed in conventional quantum well laser devices. A second device structure, employing a similar structure to that of the first device, employs new quasi-ternary compounds with compositions outside of the miscibility gap of corresponding quaternary compounds for quantum wells in GaSb— or InAs-based laser devices which extend performance of mid-infrared laser devices operating in the 2.2-4.0 &mgr;m range. The semiconductor diode laser may be formed so as to operate having a multi-mode or single-mode radiation.
